Question

How do you know if you're double-jointed?

Answer 1

there is no such thing as being double jointed. just flexible.

Answer 2

Try "locking" your joints - such as your fingers, your elbows, your knees - and see if they bend past what's normal.

Answer 3

if you just typed this with your feet  the that's how you know! lol

as your limbs will be able to rotate more than anyone elses, and seemingly get into all sorts of funny shapes!
